Disable PrivateDevices for Galera on CentOS 7
This patch adds the `galera_disable_privatedevices` variable that
allows deployers to disable PrivateDevices in the systemd unit file
shipped with MariaDB 10.1+ on CentOS 7 systems.

This is a workaround to fix the systemd/LXC issues with bind
mounting an already bind mounted `/dev/ptmx` inside the LXC
container.

See Launchpad bug, lxc/lxc#1623, or systemd/systemd#6121 for more
details.
